Patented Feb. 6, 191'?.

Original application filed September 28, 1916, Serial No. 122,662.Divided and this application filed December 11, 1916. Serial No.136,327.

To all whom t may concern:

Be it known that I, RICHARD ALBERT MIN- TERN, a subject of the King ofGreat Britain, j

residing in lVilson street, Horsham, in'the State of Victoria,Commonwealth of Australia, have invented new and useful Improvements inCultivating Implements, of.y

which the following isa specification.

This invention relates to improvements in wheeled implementsand itresides particuy larly in the provision of means whereby a high wheelcultivator vcan be operatively connected to the front of a seed drill orworked separately as designed. The invention, furthermore, embodiescertain novel features of construction and arrangements of parts whichserve to make the traction and running gear of the cultivator economicaland highly eflicient in use.

The present application is a division of my application filed September28th 1916, Serial No. 122662. Referring no-w to the accompanying sheetsof explanatory drawin s:-

Iigure'l is a view in plan of a wheeled implement constructed inaccordance with the invention and showing parts of the implement removedfor convenience of illustration.

Fig. 2 is a viewin side eleva-tion showing' the implement `of Fig. 1tted to a second implement of ydiif'erent specic character, such forinstance as a seed drill. l

Fig. 3 is a viewin plan of parts of the cultivator and a seed drill andshows the manner of detachably connecting the two implements.

In the dra-wings like characters of reference have been employed toindicate similar or corresponding parts in the different views and thenumerall designates a stout axle 'beam of angle iron the ends of whichare tted withzcranked stub axles 2 on which are mounted high transportwheels 3; The stub axles 2 are secured removably to the ends of the beam1 by means of'collars 4 and -bolts 5 or thevlike means. `A frame 6 madeof light angle iron and reinforcing bars' 61 of the same material ispivotally mounted on a rod 12 which is supported in projections 62fitted to the stout beam 1 at suitable points.

The central part of the axle beam 1 is furnished with a forwardlyprojecting beam 7 formed of one stout or two light angle iron bars andto the forward end of said beam. is

fitted a casting 8 having a vertical boss 9 for accommodating the post10 of steering wheels 11 of approved form. The axle beam 1 and theforwardly extending beam 7 form a rigid T-shaped frame for supportingthe operative parts of the implement. Invlieu of employing a pair ofsteeringwheels 11 as shown in the drawings, I may'substitute anystandard arrangement of steering wheels.

The rear end of the beam 7 is rigidly mounted4 on the center of the beam1 and its forwardfe'nd' is'stayed by 4diagonal bars 12 which are clampedto the said beam 1 at 13.

A vertical guide not shown is fitted'to the center ofthe front member ofthe frame 6 and extends on each side the beam 7 so as to guide theframe6 and maintain the same against lateral stresses 'in position and topermit of the forward part of the said frame 6 being raised and loweredas desired. The guide-just mentioned is connected with stays such as 16which'extend across the top of 15 toward the ends` Vof frame 6 and.insure rigidity to the'structure under all ordinary working stresses.

- A quadrant 17 is fitted to the beam 7 and a bolt 18 passing throughthe forward leg of said quadrant pivotally supports a. lever 19. Theforward en d of the lever 19 is connected by a link 20 to the forwardpart of the frame 6 and by operating` said lever the forward end of saidframe 6 can be raised and lowered as and when required.

The lever 19 isfurnished with a pawl 21 which is adapted to engage withthe teeth of the quadrant 17 in the usual manner.

The ends of the front bar of the frame 6 are fitted with dependingbrackets 22 which are designed to support the ends of a bar 23.

f The forward ends of yoke-shaped sections 2A are pivotally mounted onthe bar 23 and to the said Isectior'ls are clamped a plurality of tynes25 furnished wit an approved form of share 26.

Two or Ymore standards 27 are fitted near to the back of the-frame' 6and a transverse rod 28 is mounted in bosses formed on the upper`endsofV said standards." :Alever 29 I is fitted rigidly to the rod 28and projects section 24 and a link 31 connects the outer end of said armto the section directly beneath. The lever 29 is provided with a pawl 32which is adapted to be engaged by the teeth of a quadrant 3B fitted tothe frame 6 for holding lever 29 in adjusted position.

The lever 29 is operated to raise and lower the back ends of thesections VE24 as desired and to facilitate the raising operation astrong tension spring 34 is arranged to exert a constant forward pull onthe lever.

The beam 1 is provided with a detachable seat 35 for the driver and theoperating levers 19 and 29 are placed so as to be grasped convenientlyby the driver when seated thereon. The forward end of the beam 7 isadjusted on the post 10 of the steering wheel 11 by moving a collar 41on said post to the position desired and then clamping itfirmly by meansof al set screw 42. Diagonally disposed hauling bars 48 are secured tothe beam 1 at their rear ends and their forward ends are connected tolinks 49 which pass forwardly and embrace the bar 45. A hook 50 isfitted to the forward end of the links 49 to engage the swingle tree towhich the draft animals are coupled.

When the implement is intended to be used with a seed-drill the driversseat 35 and the traveling wheels 3 and their axles 2 are detached fromthe beam 1. When the parts above-mentioned are detached the rear part ofthe beam 1 on the frame is connected by means of bolts 36 to the crossbeam 37 at the forward part of the rectangular drill frame therebyplacing the cultivator directly in advance of the drill hoes. It will beseen that the beam 1 has a vertical web at its rear edge which can befirmly attached to the vertical web at the front edge of the member 37.

In order to insure greater rigidity in the connection between thecultivator and the seed-drill frame the rear ends of the diagonal bars12 are formed with extensions 88 which are clamped to the seed-drill at39.

The wheels 3 are identical with those on the seed-drill and as oneset ofwheels can Y be used for both implements economy is effected.

When the cultivator is connected to a seed-drill as above described thecombined implements will be -found extremely useful for tilling fallowedland, sowing grain and distributing manure in the one operation.

The cultivator will operate as efficiently as those at present in useand its novel con* struction will facilitate its connection to andoperation with a seed-drill in such a way that economy will result infarming operations.

The implement can be made in different sizes and the constructionalparts thereof suitably modified to suit seed-drills of various sizes ormake without departing from the spirit and scope of the invention.

What I do claim is 1. A wheeled implement having an axle beam, removableaxles on the ends of said beam, transport wheels carried by said axles,a beam fitted to and extending forwardly from the center of the axlebeam, diagonal bars connecting the forwardly extending beam to the axlebeam, rearward extensions on said diagonal bars, and clamps and boltsfor connecting said extensions and said axle beam, respectively, to theframe of a supplemental wheeled implement. 2. The combination of animplement having an axle beam provided with a vertical web at its rearedge, a beam fitted to and extending forwardly from the center of saidaxle beam, diagonal bars connecting the forwardly extending beam to theaxle beam, said bars having rearward extensions projecting beyond saidaxle beam, with a second implement having a cross beam at its front end,said cross beam having a web at its front end adapted to fit closelyagainst the vertical web of said axle beam and to be firmly clampedthereto, and means whereby said extensions may be fastened to saidsecond implement.

3. A wheeled implement having an axle beam having a vertical web at itsrear edge, removable axles onthe ends of said beam, transport wheelscarried by said axles, a beam fitted to and extending forwardlj7 fromthe center of said axle beam, diagonal bars connecting the forwardlyextending beam to the axle beam, said bars having rearward extensionsprojecting beyond said axle beam, and means whereby said extensions andsaid web may be fastened to a supplemental implement frame.

In testimony whereof I aiiix my signature in presence of two witnesses.
